Getting your period twice a month can be caused by a variety of factors, including hormonal imbalances, stress, lifestyle changes, or underlying medical conditions such as uterine fibroids, polyps, thyroid disorders, or perimenopause. Some common reasons are:

• Hormonal imbalances that affect ovulation and menstrual timing.
• Stress or significant changes in weight, exercise, or diet.
• Birth control methods causing breakthrough bleeding.
• Uterine fibroids or polyps causing abnormal bleeding.
• Perimenopause causing irregular cycles as hormone levels fluctuate.
• Thyroid disorders disrupting the menstrual cycle.
• Conditions like endometriosis or polycystic ovary syndrome (PCOS).

If the occurrence is persistent, heavy, or accompanied by other symptoms like pain, consulting a healthcare provider is important to identify and address the cause properly.
